jason made me custom upper cups to work with ART arms and it has dual holes in the cup to run dual 5/8 line out the side..there the same height as the ART cup but straight cut not angled..works like a charm
well great that i got some great info. and i would really much rather have a set of your cups jason so i don't have to screw with having problems getting the fittings in there. i heard it is difficult to get fiitings for bigger ports/line on an art cup.
and jason about the cups your making for art arms. it is also possible to have matching lower cup for them too. i'm not really funded enough now to get the arms yet, but i do plan on upgrading in the future to them?
